SPECIFICATION forming part of Letters Patent No. '"83,75, dated February' 2d, 'iiIOI Application filed February 13, 1903. Serial No. 143,193.

Be it known that we, 'Il/Hannes CLARENCE IJooLn, a resident ot' Evanston, and JAnrns P. Dine, a resident of Chicago, in the county o'l Cook and State oi' Illinois, have invented certain new and useiul Improvements in Holding Devices for Index-Cards; and we do hereby declare that the following' is a full, clear, and exact description thereof, reference being' had to the accompanying drawings, and to the letters oi' reference marked thereon, which form a part of this speeiiication.

This invention relates to improvements in holding devices for detachably holding or retaining in index drawers or cases index-cards, such as are used for indexing or reference.

rlhe invention consists in the matters hereinaiter set forth, and more particularly pointed out in the appended claims.

In the accompanying drawings, illustrating our invention, Figure 1 is a plan View of a drawer for index-cards embodying our invention. Fig. 2 is a central longitudinal section thereof. Eig. 3 is a cross-sectional View thereof, taken on line 3 3 ot' Fig. 1. Fig. 4 is a detail plan section taken on line 4 4 of Fig. 3. Fig. 5 is a fragmentary view oi' the lower edge of one ot the index-cards to be placed within the holder or drawer, said ligure illusn trating the holding-notch in said Ainderxcard. Fig. 6 is a plan view showing 4a drawer for index-cards embodying a somewhat different form oic device embodying the principal features of our invention. Fig. 7 is a cross-sec tion taken on line 7 7 oi' Fig. 6. Fig. 8 is a detail plan section taken on line 8 8 ot' Fig. 7.

As illustrated in said drawings, A indicates the bottom wall ot' the drawer or receptacle, A the front wall, and A2 the rear wall thereol".

A:g A:i indicate the side walls oi' the recep* tacle.

I B indicate two holding-rods which ex tend horizontally and parallel with each other from front to rear of the drawer a short olistance above the bottom thereof. Said rods are movable both endwise and laterally. Attached to the front wall A of the drawer is a horizontal guide-plate C, and attached to the rear wall isa like guide-plate Il. biaid guide plates C and l) extend inward Vfrom the walls to which they are attached and are provided cach with two oblique guide-slots o c, l if. The guide-slots in each plate are arranged at an angle to-each other and inclined in oppositeI directions; but the slots in the two plates are alike in inclination and arrangelncl'll'.. rIhe holdingl rods or wires E B are inovidcd at their 'forward and rear ends with vertical parts or studs b, which extend downwardly through the oblique slots c o and I il, the saidV rods B B being made ol such length or the studs o being so located with respect to each other that when the said studs are engaged with the oblique slots c e and el d and both rods are moved forward in an endwiso direction the studs at both ends oiI the rods will engage the forward or separated ends oi both sets of said slots c o and l nl, and when said rods are moved backward said studs will likewise engage the adjacent or rear ends of both sets of slots.

Located in the `forward part oil the drawer is an actuatingdever E, which is arranged to swing in a vertical plane, is pivoted at one end to the bottom olI thedrawer near one side oi the same, and has its iree end located beneath and closely adjacent to the forward guide-plate C. As herein shown, said lever is pivoteol to the bottom oi the drawer by means of a pivot stud or screw c. The irce end of the lever E is bent around the guideplate C and is then directed upwardly to forni a rigid standard E', located centrally over said guide-plate. Said standard E/ is provided with a notch c' in its upper end, which notch is engaged by the curved edge oi? a spirallyformed cam-plate E, attached to a horizontal rod E, which passes through the lront wall A' ol the drawer and is provided at its outer end with a knob Ei, by which said rod may be turned and the cani-plate I1" thereby actuated. Said cam-plate E is so shaped that when the knob is partially turned its spirallyformed edge by its engageinihit with the notch in the standard E will move the Free end ot' the lever E toward and 'from the `liront wall of the drawer. Said lever is provided below the l guide-plate C with a longitudinal slot c2, into which the depending ends or studs /1 on the rods B B project. Said studs 7; fbeing engaged with the oblique slots in the guideplates C and D and also with the longitudinal slot c2 of the actuating-lever E, when the free i end of said actuating-lever, in which the slot is.formed, is moved toward and from the front end of the drawer or in a direction endwise of the rods the actuating-lever will shift ori move the rods endwise, and thus carry their studs backwardly or forwardly in the oblique slots c nl, with the effect of drawing said rods together or spreading' them apart, the rods being in the construction illustrated spread apart or separated when the ends of the rods are engaged with the forward parts of the slots c (Z and being brought together when the rods are thrust rearwardly and their ends are brought into engagement with the rear ends of said slots c (Z.

The cards which are inserted into the drawer or case and which are to be engaged by the holding-rods B B will be provided with notches in the lower surfaces of T formvsuch, for instance, as are indicated at J in Fig. 5, which shows the lower part of one of said cards provided with the slot j. Said cards are inserted in the case or drawer when the holding-rods are drawn together, the rods passing' through the narrow part of the slot f, and when the cards are in place the rods are spread apart and are thus engaged with the wider upper part of the slot f, whereby the cards are prevented from accidentally slipping out of the drawer. l

From the construction described it will be obvious that by turning the knob F2 the holding-rods B B may be brought together, so that the index-cards may be placed in the drawer and the rods engaged with the slots in the lower edges thereof, and the rods may be then spread apart to engage the upper horizontal part of the key-shaped slot in the said indexcard.

For limitingI the turning movement of the knob Fi! and the cam-plate F a radial pinf is inserted through the rod F and a stop-pinf/ is inserted in the inner face of the drawer in position for contact with said radial pin. The radial pinfprojects from both sides of the rod F and by contact of its opposite ends with the stop-pin f' prevents the cam from being' turned more than half of a complete rotation, the working edge of the cam-plate preferably being extended through somewhat more than a half-circle.

In Figs. 6 to S we have shown a somewhat different form of construction in a device embodying the main feature of our invention. In this instance the drawer is made in the same manner as before described and is provided with guide-plates C and D at its front and rear ends and holding rods or wires adapted to engage at their ends with oblique l slots c c, (Z fZ in the said guide-plates in the same manner as before described.

ln this instance. an actuating-lever Ff 1s arranged in the forward part of the drawerand 1s pivoted 5 at one end of the dra-wer Vand extends transversely across the same to the opposite side thereof. As shown in the drawings, said lever is pivoted to the bottom of the drawer by means of a screw e3, while its opposite or free end is located in an opening a, formed in the opposite side wall of the drawer, the free endY of the lever E" being` preferably turned upwardly to form an arm c4, which constitutes a finger-piece by which the lever may be readily moved backward or forward. The portion of said lever E3 adjacent to the guide-plate C extends beneath and closely adjacent to said guide-plate. The swinging of the free end of the lever E3 has the effect of moving' the central part of the arm, which is beneath the guide-plate. C, horizontally toward or from the front wall of the drawer or in a direction endwise of the holding-rods. In said lever E below the guide-plate is formed a longitudinal slot ci", and the downturned ends of the holding-rods B B project through the said guideslots c c into the slot e", so the ends of the holding-rods engage both the oblique slots c c and the said longitudinal slot er. As a result of the construction described it is obvious that by movement of the lever E3 the holding-rods B B will be shifted backwardly and forwardly and that through the engagement of the downturned ends of said rods with the said guideslots the forward movement of the lever will, through its connection with the said holdingrods, have the eect of moving the same forwardly in the guide-slots c c andd d, with the result of spreading the rods bodily apart, while maintaining' them in a parallel relation, and, similarly, a backward movement of said lever E by shifting both of the rods backwardly in said guide-slots will have the e'ect of bringing them together.

V e claim as our inventionl. The combination, with a receptacle, of a holding' device for index-cards or the like, comprising two endwise and laterally movable, parallel, holding-rods provided at their ends with vertical studs, stationary, horizontal guide-plates secured to the end walls of the receptacle above the bottom of the same and provided each with two oblique slots which in the two guide-plates are inclined in the same direction and through which the studs on the rods extend, and an actuating-lever which is pivoted at one end to the receptacle and at its opposite end has sliding engagement with one of said guide-plates, said lever having in its end which engages the guide-plate a slot arranged transversely with respect to the holding-rods and adapted for engagement with the studs on the adjacent ends of said rods.

The combination, with a receptacle, of a IOO IIO

holding device for index-cards and the like, comprising two endwise and laterally mov able, parallel, holding-rods provided at their ends with vertical studs, stationary, horizontal guide-plates located at the ends of the receptacle above the bottom thereof and provided each with two oblique slots which in the two guide-plates are inclined in the same direction and through which said studs on the rods extend, a horizontally-arranged actuating member arranged to slide on one of said guide-plates andvprovided with a slot arranged transversely with respect to the holding-rods and adapted for engagement with the studs on the adjacent ends of the rods, and a rotative rod extending through the end Wall of the receptacle and provided with a spirallyformed cam-plate; said actuating' member being bent upwardly at one of its sides to form a standard which is notched at its upper end to engage said cam-plate.

3. The combination, with a receptacle, of a holding device for index-cards and the like comprising two endwise and laterally movable parallel holding-rods provided at their ends with vertical studs, stationary, horizontal guide-plates at the ends of the receptacle provided each with two oblique slots which in the two guide-plates are inclined in the same direction and through which the studs on the rods extend, an actuating-Jever pivoted at one end thereof to the receptacle having at its free end a slot arranged transversely with respect to the rods and adapted for engagement with the studs on the rods at one end of the receptacle, said lever having sliding' engagementat its free end with the adjacent guideplate and being provided with an upwardlyextending standard, and a rotative rod extending through the end wall or' the receptacle and provided with a spirally-forined cam-plate which engages the said standard on the actuating-lever.
